Answer:

The total cost is $41.

Explanation:

The given expression is :


3r+2.5p

Now we know that the roses are represented by = r

And the petunias are represented by = p

So, we can say that each rose costs $3 (3r) and each petunia cost $2.5 (2.5p)

So, we can now find the total value of 7 roses and 8 petunias.

Cost of 1 rose = $3

Cost of 7 roses is =
7*3=21

Cost of 1 petunia is = $2.5

Cost of 8 petunias is =
8*2.5=20

Total cost of the flowers =
21+20 = $41.
